I am doing an assignment that is to calculate the federal tax based on the users input. I am not entirely sure what it is doing, but it is definitely not what I want it to do. I commented out the loops because they seemed to have caused a problem, but there is still problems that are making the program do something else. Here is my code:
#include<iostream>
#include<string>
using namespace std;
double getData();
double taxAmount();
[Code] ....
Functions just seem like they are not my thing. It never gets to the second function to do the calculations and then return to main to display the results.
I tried changing the code to a switch(status) with a default: at the end that looped the "please try again" but for some reason, that was a fail, it created an endless loop.
How I can let the user input a certain operator into this calculator function?. I would like to use cin to input the operator if possible because it is one of the only input commands I know.
// Calculator.cpp : Defines the entry point for the console application. // Calculates the value of two numbers based on the four main operations.
#include "stdafx.h" #include <iostream> int add(int x, int y); int subtract(int x, int y); int multiply(int x, int y); int divide(int x, int y);
I am working on a simple calculator in C++ .... All works fine with the calculator up until the requirement for the user to input "do you want to go again y/n" .... What i want to happen is the screen to clear down and reloop to the enter name part....but i can't get it to do that
Program Description: To write and develop a programme where a user can input a cost or price of something before VAT our program must then process the input number and must output the price with the original value plus VAT
#include <iostream>// I must use this to start my programming #include <string> // I have added this for the extension task so the user has to input their name #include <iomanip> // this is to manipulate the text #include <stdlib.h> using namespace std; // using the "using namespace std" shows that i will be using standard text throughout this programme
My assignment is to pixelate an image based on users input. I have a structure that stores the image, and in this structure I'm storing the height and width and a dynamic array of RGBA struct.
This is my function. my main issue (that I've found) is offsetting and figuring out a way to handle the "edge" if the dimensions don't add up to the set pixelation size.
how to stop outputting data based on a user input. The text file is as follows:
1. a 2. b 3. c
and the code I'm using is as follows:
int main (){ string line; int search; cout << "Enter a number from 1-3" << endl; cin >> search; search++; ifstream myfile ("example.txt");
[Code]...
What I want to do is to just output number 1 (the whole line) if the user enters number 1. However, I get an error on the second condition w/c is the "&& line!= search"
I'm trying to create a function where it allows the user to type in multiple amounts of integers, so if the user wanted to have 3 different storages that hold different integers, the input would look something like this:
5 97 12 31 2 1 //let's say this is held in variable "a" 1 3 284 3 8 // "b" 2 3 482 3 4 // "c" 2 3 4 2 3 // "d" 99 0 2 3 42 // "e"
Since we don't know what number the user will input every time, I'm not sure how to create a dynamically allocated array that will create an x amount of arrays every time.. I want to be able to access each index of a, b, c, d, e or however many arrays there are.
So far, this is what I have, but I'm having trouble creating the arrays since it's unpredictable. I'm purposely not using vectors because I don't really get how pointers work so I'm trying to play around with it.
int* x; int length, numbers; cin >> length; x = new int[length] for (int i=0;i<length;i++) { cin >> numbers; //this doesn't work because it only grabs the first line for some reason x[i] = numbers }
I am trying to create a program that will calculate pi based on a user input for accuracy. If the user input .3 then when the leibniz infinite sum value at a particular i becomes less then the input of .3 then the loop will exit.
I have looked at a number of examples on the internet but I feel lost. I have put together working code that will infinitely output sums but I need the loop to stop when the sum value is less then the accuracy value.
My question is what is wrong with my while loop, why will it only give me infinite summations? How do I make it so that the loop will exit when my accuracy input is greater then the sum?
int main () { double accuracy; cout<<"Give an accurate number." << flush;//looks nice cin>>accuracy; int d;//initialize denominator double pi = 0.0; while(accuracy < d){
i want to display all the contents of a file excluding one based on user input say i have 4 records in the file numbered 1 to 4....the user chooses 2 to exclude it outputs records 1,3,4,4 when it should be records 1,3,4 what am i doing wrong here is the code.its basically displaying the last record in the file twice
I need to create a program that prints a certain number of asterisks based on user input. The user inputs 5 and I want my program to output "*****". How would I do this in C? I've tried printf("%#**", myvariable) but this does not work it only prints "*".
Write a program to generate a report based on input received from a text file. Suppose the input text file student_status.txt contains the student’s name (lastName, firstName middleName), id, number of credits earned as follows :
Doe, John K. 3460 25 Andrews, Susan S. 3987 72 Monroe, Marylin 2298 87 Gaston, Arthur C. 2894 110
Generate the output in the following format :
John K. Doe 3460 25 Freshman Susan S. Andrews 3987 40 Sophomore Marylin Monroe 2298 87 Junior Arthur C. Gaston 2894 110 Senior
The program must be written to use the enum class_level :
The function deriveClassLevel should derive the class_level of the student based on the number of credits earned.
The first namespace globalType tys should derive the class level based on a two year school policy. and the second namespace globalType fys should derive the class level based on a four year school policy.
Four Year School Policy: Freshman 0-29 creditsSophomore 30-59 credits Junior 60-89 creditsSenior 90 or more credits
Two Year School Policy: Freshman 0-29 creditsSophomore 30 or more credits
NOTE : use ignore() function with ifstream objects whenever you want to ignore the newline character.
For example : ifstream transferSchoolFile ; transferSchoolFile.open("student_status.txt", ios::in);
while( !transferSchoolFile.eof()) { getline(transferSchoolFile,name) ; transferSchoolFile >> id >> credits; transferSchoolFile.ignore(); //Used here to ignore the newline character. …. }
I did this in parts so I got it working with a four year criteria without the user defined name spaces.

I have am having a bit of trouble with a baisc calculator that I am writing for my intro to programming class at Uni. We are using the C programming language. The program is supposed to be able to add, subtract, multiply, and divide. It is also supposed to return certain messages if an error has occurred. This is how the program is supposed to perform:
bash-4.2$ ./calc enter expression: 4.25 * 3.3 result: 14.025
In my calculator, I am trying to make it so that you put enter 1 to add, 2 to subtract, 3 to multiply, and 4 to divide. I am facing the issue of making it so that you must enter a number, however instead of it being any number, it must be 1, 2, 3, or 4, and if it is not any of those numbers, you must re-enter the number. Here is a little snippet of my code:
Code:
printf("Please enter 1 to add, 2 to subtract, 3 to multiply, or 4 to multiply: "); while (scanf("%d", &input) != 1) { while (getchar() != ' '); printf("Invalid option. Please try again: ");
I'm writing an addition and subtraction calculator that takes input as: 5+6-3+2. You should be able to add or sub as many numbers as you want. I want the while loop to stop when the user hits enter. I put the getchar() function to catch the and break the loop but it is also swallowing the '-' sign, which I want to use to subtract and is instead adding the numbers with "sum+=number". How can I get around that?
Code:
#include <stdio.h> int main(int argc, char *argv[]){ int number, sum = 0;
i'm trying to write a calculator. the user will enter the terms and they will be stored in arrays. i will be storing those terms in string arrays and then later turn them to double to work with them. but the user should be able to enter terms like sin(252) and the program should be able to recognize it and calculate it.
I have my Reverse Polish calculator compiling and everything but for the assignment I need to handle a few exceptions that I can't seem to get. First off I'm trying to make the program exit if the user enters only "0" but since the input i'm using is string, I cant figure out how to code
"If the first node is 0 and the next node = NULL, return true"
Here is my code: #include<iomanip> #include<iostream> #include<stdlib.h> #include<stdio.h> #include<string> #include<sstream> using namespace std;
i can't seem to get my program to save the Set.savv file and encrypt it and decrypt it when user logs back on to there virtual file on a CD and writing it to the disk its self and closing the session
Player is given choice of x number of Races This choice changes the player's base stats. Then player is given a choice of x number of Classes (archer, warrior, etc.) This choice determines how the player's stats will change upon leveling up.
I'm trying to get the hang of the declaration and use of char. I'm trying to write a program that reads sentences from the user and changes them based on their character choices, I keep getting load of compiler errors.......am I off to a good start or am I way off?

I have an extra credit project where I'm supposed to calculate an approximate the user's age based on the current date and their birthday. My problem is that I am not getting the proper date and time. C++ keeps giving me some random date. I looked up c++ time format on the internet because this is extra credit and not in my book.
I am currently using dev C++ 4.9.9.2. Here is my current code :
// included libraries #include <cstdlib> #include <iostream> #include <iomanip> #include <time.h> #define cls system("cls") #define pauseOutput system("pause") void printM(int x); void age(int m, int d, int y, int &yearAge, int &monthAge, int &dayAge);
